Senova Systems, a Californian spin-off company based on pH sensing technology co-invented by Dr Wildgoose (School of Chemistry, UEA), has announced the release of it's first generation of revolutionary solid-state, calibration-free pH sensors that will begin shipping in the third quarter of 2012.

pH (the measure of a solution's acidity or alkalinity) is one of the most crucial measurements during the production or processing of just about everything we touch or consume – from the food we eat, the soap and toothpaste we use to the clothing and cosmetics we wear and the medicines we take. Conventional glass pH probes are built on the same technology that was developed over 70 years ago and haven't changed much in that time – until now. Glass probes are fragile and require constant recalibration before accurate readings can be made over periods of time. They are also subject to fouling and blocking of the fragile glass sensing membrane with which they sense the concentration of protons (pH) in solution.Senova's new "PHit™" sensors represent "a genuine breakthrough to solve so many of the costly and frustrating limitations associated with today's glass pH electrodes". They are made from robust carbon substrates that have pH sensitive molecules chemically attached to the surface of the probe. Proprietary technology means they are continually self-calibrating. Together this means no more broken probes and no more messy calibration solutions or wet-storage solutions are required! Senova Systems will be showcasing the PHit sensors at Pittcon booth #2482, from March 12th-15th.To find out more go to http://senovasystems.com/press-release/phit-ph-meter-introduction.
